SpaceX sea landing fails thanks to a broken leg (updated)

So much for SpaceX's successful ground landing representing a sign of things to come. SpaceX has confirmed that the first stage of its latest Falcon 9 rocket suffered a "hard landing" on its attempt to land at sea, breaking one of the landing legs and sending the vehicle crashing down.
